What colour does litmus paper go in acid?
Litmus paper usually turns either blue or pink (sometimes red) which indicates whether the chemical is an acid or a base. If the paper turns blue it is a base. If pink or red it is an acid.
What substance is used to determine the presence of an acid or base?
by using an indicator like litmus paper!!!
When do red and blue litmus paper tail to turn color?
Red litmus paper stays red in the presence of an acid and turns blue in the presence of a base. Blue litmus paper stays blue in the presence of a base and turns red in the presence of an acid.
Acids causes litmus paper to turn into what color?
HCl (hydrochloric acid) is an acid so it will turn litmus paper red. and alkali will go from red litmus to blue.
What colors do litmus paper and phenolpthalein turn in presence of an acid or of base?
Litmus paper: red color in acidic solutions and blue color in basic solutions.Phenolphthalein: no color in acidic solutions.
How can you determine if substance is acid or base?
pH paper and litmus paper
What color does litmus paper change if base or paper?
When litmus paper touches an acid, the paper changes to red. When it touches a base, the paper changes to blue. By comparing the color the litmus paper changed to by a chart, you could determine how strong or weak that acid or base is.
What things could be used to determine whether a substance is an acid or a base?
litmus paper.
What color does red litmus paper turn into from a acid?
Red litmus paper remains red when dipped into an acid. Blue litmus paper will turn red in an acid. Similarly, Blue litmus remains blue in a base. Red litmus turns blue in a base.
What is the word and symbol chemical equation for litmus paper reacting with a acid or base?
Litmus paper is an indicator that turns red in acidic solutions and blue in basic solutions. The chemical equation for litmus paper reacting with an acid could be: H+ (from the acid) + Litmus paper (Red) -> Litmus paper (Blue). Similarly, the equation for litmus paper reacting with a base could be: OH- (from the base) + Litmus paper (Red) -> Litmus paper (Blue).
Which litmus paper do you use to identify an acid and how does it react?
Online science class does not mean you can just google for answers. Read your textbook!
What happens to litmus paper touches an acid?
When blue litmus paper touches an acid it becomes red. This is the type of litmus paper that detects acids. When red litmus paper touches an acid, it will remain red. This is used to test a base.

Way back when I was in high school (3000 BC) acid turned litmus paper pink and a base turned it blue.
Mandy is testing an unknown solution to determine whether it is an acid or a base She places a piece of red litmus paper into the solution and the paper turns blue?
it is base
What paper do you use to test for pH?
Litmus paper will determine acid or base. Universal indicator paper (pH paper) will give an answer to the nearest whole number.
You are given an unknown solution and asked to determine if it is an acid or base You test the solution with a piece of litmus paper You notice the litmus paper turns blue in color This tells you t?
The solution is a base. ( If it turned red, then the solution would be classified as an acid.)
